Have you ever been in a love relationship??

I have fell in love but he is never left me. I have not experienced of someone living me alone and going whom I love seriously. But its really a horrible experience. I have one of my friend who is undergoing such a situation. Its really horrible. From 3 years they loved each other but that guy never agreed to get married to her. Because of his family. He doesnt want to go against his family. Nor he is not interested to get married to her. But this girl really loves him and wants to get married to him.She is really suffering, I can really feel her problem. I wish nobody will have such kind of situation...
